I just bought one of these bags for a trip to Indo. No affiliation with FCS.

As most of my boards are pretty thick, I was a little concerned as to how many boards I might have actually been able to get into the bag. As I purchased it online I didn't have to hide to ask a shop to try it out first.

Stoked to be able to say that most people should be able to get 4 boards in unless you have super wide thick boards.
